[TE stares ANGELINE M. BAR/HAM, OF PHILADELPHIA, MISSISSIPPI.

{BATTING-SHUTTLE.

T 0 all whomit may concern Be it known that I, ANGELINE M. BARH'AM, acitizen of the United States, residing at Philadelphia, in the county ofNeshoba and State of Mississippi, have invented certain new and usefulImprovements in a Tatting Shuttle, of which the following is aspecification.

This invention relates to tatting shuttles.

The object of the invention is to provide a shuttle of this characterequipped with a removable bobbin similar to a sewing machine bobbinwhich may be readily wound on a sewing machine and inserted in theshuttle, and yieldably held therein.

Another object is to provide improved means for holding the bobbin inthe shuttle and prevent the too rapid feeding or unwinding of the threadfrom the bobbin.

Another object is to provide a tatting shuttle with a longitudinallyextending nose having a hooked terminal to be used in loosening thethread.

Another object is to provide a shuttle of this character equipped withsimple and efficient tension means for preventing the thread beingunwound too rapidly from the bobbin when using the shuttle.

With these and other objects in view the invention consists of certainnovel features of construction as hereinafter shown and described andthen specifically pointed out in the claim, and in the drawingsillustrative of the preferred embodiment of the invention.

In the accompanying drawing Figure 1 represents a side elevation of ashuttle constructed in accordance with this invention with parts brokenout and in section. I

Fig. 2 is a plan view thereof;

Fig. 3 is a transverse section; and

Fig. 1 is a detail sectional view showing the tension means for holdingthe thread.

The shuttle 1 constituting this invention is preferably made boat shapedas shown with a cavity 2 to receive and retain the thread carryingbobbin 3 which is similar to bobbins of this character used in sewingmachines constituting a rod with disk like heads 4: at its oppositeends, said rod projecting beyond said heads to form journals torotatably mount the shuttle in the bobbin. The end walls of the recessor cavity 2 are provided with bearings 5 and 6 extending longitudinallyof the shuttle to receive said Specification of Letters Patent.

Application filed April 30,

Patented Sep 1925 1921. Serial in. 465,684.,

journals, the bearing 5 having a slot 7 eX- tending therefrom throughthe outer face of the shuttleto provide for the insertion and removal.ofthe bobbin. A spring 8v is mounted in the opposite end of the shuttleand has an eye through which the journal at one end of the bobbin isdesigned to be passed before it enters the bearing 6 so that the bobbinwill be yieldably held in the shuttle to provide for its ready insertionand removal and to operate as a brake to prevent the too rapid unwindinof the thread from the bobbin.

One en of the shuttle l is provided with a longitudinally extending nose9 equipped at its terminal with a hook shaped pick 10 designed tobe'used for loosening the thread preferably against one of the innerwalls of the recess or cavity 2 so that it will not interfere with thepassage of the shuttle through the work and which will prevent thethread from being unwound too fast from the bobbin when tatting.

This tension device 11 is preferably constructed in the form of a springmetal buttonmounted on a pin 12 projecting laterally inward in theshuttle, and the face 13 of said button has yieldable engagement withthe adjacent wall of the shuttle between which and said wall the threadfrom the bobbin is designed to pass and be yieldably held to prevent itbeing too rapidly unwound from the bobbin. Shuttle 1 may be constructedof any suitable material as may also the bobbin 3. To remove the bobbinwhen inserted as shown in Figs. 1 and 2 all that is necessary is toexert the longitudinal pressure against the head 4: which bears againstspring 8 thereby releasing the journal at the other end thereof from thesocket 5 and permitting it to slide through the slot 7 whereby thebobbin may be readily taken out of the shuttle for winding orreplaceabove described permits the use of an ordinary sewingmachinebobbin and thereby effects a great saving in time in the winding ofthese bobbins which is usually done by hand.

The shuttles are extremely simple and cheap to manufacture being formedentirely of one piece of material except the spring 8 and the tensiondevice 11.

The preferred embodiment of the invention is disclosed in the drawingsand set forth in the specification, but it will be understood that anymodifications Within the scope of the claimed invention may be made inthe construction Withoutdeparting from the principle of the invention orsacrificing any of its advantages.

What I claim is A boat-shaped tatting shuttle having a I bobbin chamberwith bearings in its ends, a

bobbin having journals for insertion in said bearings and a tensiondevice for the thread fed from said bobbin, mounted on one side Wall ofthe bobbin chamber and constructed in the form of aspring metal button,one face of which has yieldable engagement With the adjacent Wall of thebobbin chamber, between Which and said Wall the thread from the bobbinis designed to pass and be yieldably held to prevent its being toorapidly unwound from the bobbin.
